Synthetic method of chiral piperazidone derivative

The invention relates to a synthetic method of a chiral piperazidone derivative. The synthetic method comprises the following steps: performing an oxidation reaction on ethanolamine with a protectivegroup in a formula (I) to obtain aminoacetaldehyde with a protective group in a formula (II); in an alcohol solvent, performing a reduced amination reaction on the aminoacetaldehyde with the protective group in the formula (II) and amino acid ester in the presence of a reducing agent to obtain the chiral piperazidone derivative in the formula (II), wherein the reduced amination reaction temperature is -10 DEG C to 0 DEG C, and the amino acid ester is L-type amino acid ester or D-type amino acid ester; and in the alcohol solvent, performing a de-protection reaction on the chiral piperazidone derivative in the formula (II) and forming a ring to obtain a chiral piperazidone derivative in a formula (IV), wherein a reaction route is shown as follows: the protective group X is benzoxo carbonyl or tert-butyoxo carbonyl; R is methyl, ethyl, isopropyl, isobutyl, hydroxyethyl, benzyl, p-hydroxybenzyl and the like; and R' is methyl, ethyl and the like.

Synthesis of piperazinones and their application in constrained mimetics of the growth hormone secretagogue NN703

The focus of this paper is the chemistry of 2-piperazinones and the use of this building block to restrict the conformational freedom of the growth hormone secretagogue NN703 (currently in clinical development). We exploit classical methods for 2-piperazinone synthesis as well as some novel approaches such as a Boronic Mannich reaction. Finally, we report on the ability of the constrained target compounds to release growth hormone in vitro.
